Zombies were also encouraged to interact with living humans along the way - all in the name of fun, although signs posted on windows and light poles instructed zombies: "No blood on local businesses. Violators will be dismembered."

Organizers explained that the event - dubbed "Red, White, and Dead" - fell on the eve of Independence Day, because they felt it patriotic to fight for the world record currently held by the Brits. It was once held by Seattle.

"Did you see the brain hanging from the American flag? I think that says it all right there," said Rocky Champagne, who dressed as a zombie businessman from the '60s. His right "eye" dangled from dark-rimmed prescription glasses.

Organizers said Sunday that 4,233 "registered zombies" came in search of brains and blood, well above the current record of 4,026. The number - and the world record - should be verified after the Fourth of July holiday.
